While The Doctor was in control of Seven, he met Jaryn, who took him to their sickbay. She showed him patients who were suffering from synaptic failure caused by a viral weapon from their photonic enemies. Seven/Doctor developed a treatment, got to know Jaryn better and developed an attraction for her. Jaryn told him about her family's photonic servant before the uprising. Later, when Ranek made amorous advances towards Seven/Doctor, he told Jaryn about Ranek's behavior. The Doctor subsequently learned that Jaryn was in love with Ranek. The Doctor/Seven became jealous and told Jaryn that she should find someone like him/her. When he pulled a neck muscle, Jaryn massaged his neck, causing sexual feelings in The Doctor side and angering the Seven side.

Ranek also developed a romantic interest in 'Seven', not knowing that Jaryn had a romantic feelings for him. When Ranek was severely injured during an attempt by the USS Voyager to rescue its crew members, The Doctor – released from within Seven's implants – operated on Ranek and saved his life, prompting Jaryn to reevaluate her opinion of holograms as she thanked The Doctor, complimenting his medical skills before he departed.
